CVE-2024-49369
CVE-2024-49369 affects Icinga 2, a monitoring system, due to flawed TLS certificate validation. This allows attackers to impersonate trusted cluster nodes and API users using TLS client certificates. The SVRS score of 30 indicates a moderate risk; while not critical, patching is still recommended to prevent potential exploits.
CVE-2024-49369 impacts Icinga 2 versions 2.4.0 and later, creating a significant security vulnerability. An attacker could exploit this to gain unauthorized access and control over monitored network resources. This impersonation allows for malicious actions and data breaches. Fixed versions are available in v2.14.3, v2.13.10, v2.12.11, and v2.11.12, emphasizing the need for immediate patching to mitigate the risk. This CVE highlights the importance of rigorous certificate validation in networked systems for cybersecurity.
Description
CVE-2024-49369 affects Icinga 2 versions starting from 2.4.0. This vulnerability is a TLS certificate validation flaw that allows attackers to impersonate trusted cluster nodes and API users who utilize TLS client certificates for authentication. This vulnerability has been patched in versions v2.14.3, v2.13.10, v2.12.11, and v2.11.12. While the CVSS score is 9.8, indicating a high severity, the SOCRadar Vulnerability Risk Score (SVRS) is 30, signifying a moderate risk.
Key Insights
- Impersonation of Trusted Entities: The vulnerability allows attackers to masquerade as legitimate cluster nodes and API users, granting them unauthorized access to sensitive information and control over the monitoring system.
- Compromised System Integrity: Attackers could manipulate system configuration, alter monitoring data, and potentially disrupt critical infrastructure operations through impersonation.
- Potential for Data Breaches: Attackers could steal sensitive data, including monitoring metrics, network credentials, and internal system logs, through access gained by impersonating trusted entities.
Mitigation Strategies
- Upgrade Icinga: Immediately upgrade to the patched versions: v2.14.3, v2.13.10, v2.12.11, or v2.11.12, to address the vulnerability.
- Implement Strong Authentication: Enforce robust authentication protocols and multi-factor authentication for all users accessing Icinga systems to mitigate impersonation attempts.
- Regular Vulnerability Scanning: Conduct frequent vulnerability scans to detect and address any potential weaknesses in the environment and ensure timely patching.
- Network Segmentation: Isolate the Icinga system from other sensitive networks to limit the impact of a potential breach.
